Description
Известны способы измерени рН растворов с помощью хингидранНого полуэлемента. Однако при этом примен ют платиновые или золотые электроды, что удорожает способы.Methods are known for measuring the pH of solutions using a quinine-half cell. However, platinum or gold electrodes are used, which increases the cost of the methods.
Предлагаемый способ отличаетс тем, что примен ют титановый электрод, предварительно обработанный раствором окислител с несколькими капл ми электролита дл золочени или платилнровани электродов. Это позвол ет удешевить способ.The proposed method is characterized in that a titanium electrode pretreated with an oxidizing solution with a few drops of electrolyte is used for gilding or plating the electrodes. This makes it cheaper.
Тита«овый электрод готов т следующим образом.Titus' new electrode is prepared as follows.
Из титановой жести марки ВТ-1Д вырезают электрод, вставл ют его в Нагретую стекл нную трубку и заливают расплавленным полиэтиленом высокого давлени . Рабочую часть электрода зачищают до блеска мелкой нождачной бумагой, тщательно обезжиривают в спирте, хромовой смеси и промывают дистиллированной водой. Затем электрод погружают в раствор, содержащий сильный окислитель, например , 0,1 н. раствор гипохлорита или 0,2 н. раствор перекиси водорода с 4-7 капл ми раствора дл золочени или обычного раствора дл платинировани электродов на 70-100 мл окислител .An HT-1D titanium sheet was cut out an electrode, inserted into a heated glass tube, and filled with molten high-pressure polyethylene. The working part of the electrode is stripped to a shine with fine scabbard, carefully degreased in alcohol, the chromium mixture and washed with distilled water. Then the electrode is immersed in a solution containing a strong oxidizing agent, for example, 0.1 n. hypochlorite solution or 0.2 n. a hydrogen peroxide solution with 4-7 drops of a gilding solution or a conventional solution for plating electrodes with 70-100 ml of oxidant.
Через 24 час электрод промывают и используют при потенциометрическом определении рН или при ацидометрических потенциометрических титровани х подобно платиновому или золотому.After 24 hours, the electrode is washed and used for potentiometric determination of pH or for acidometric potentiometric titrations like platinum or gold.
В нерабочем состо нии электроды хран т в растворе окислител .Inoperative electrodes are stored in an oxidizing solution.
Пример. Определ ют рН буферного раствора с помощью хингидронного .электрода на титане (рН буферного раствора, предварительно установленный по водородному электроду, равен 6,5). Измерени производ т на потенциометре ППТВ-1 в воздушном термостате при температуре 25±0,2°.Example. The pH of the buffer solution is determined using a quingidronic electrode on titanium (the pH of the buffer solution previously set on the hydrogen electrode is 6.5). Measurements are made on a PPTV-1 potentiometer in an air thermostat at a temperature of 25 ± 0.2 °.
Значение рН дл титанового электрода составл ет 6,51. Совпадение, результатов имеет место при потенциаметрическом- титровании кислоты Щел-очью с- применением платинового, золотого, стекл нного и титанового эле,ктродов.The pH value for the titanium electrode is 6.51. The coincidence of the results takes place in potentimetric titration of the acid with Schel-ocy with the use of platinum, gold, glass and titanium electrons, to electrodes.
